在此代码中插入图像时出错

Question

<?php
        $fortressMapping = [
            1 => <img src="<?php echo $image_url;?>">,'JG Fortress',
            3 => <img src="<?php echo $image_url;?>">,'HT Fortress',
            4 => <img src="<?php echo $image_url;?>">,'Ban Fortress',
            6 => <img src="<?php echo $image_url;?>">,'Ban Fortress',
    ];

如何在此代码中插入图像？

Answer 1

您应该像这样使用它将元素添加到数组，现场演示

<?php
    $fortressMapping = [
       1 => "<img src=\"<?php echo $image_url;?>\">,'JG Fortress'",
            .....
    ];

Answer 2

消除$fortressMapping内部的回波

<?php
$image_url = "http://example.com/image.png";
        $fortressMapping = [
            1 => '<img src="$image_url">','JG Fortress',
            3 => '<img src="$image_url">','HT Fortress',
            4 => '<img src="$image_url">','Ban Fortress',
            6 => '<img src="$image_url">','Ban Fortress',
    ];

    print_r($fortressMapping);

Answer 3

您不能在var赋值中回显：

$fortressMapping = [
            1 => "<img src='{$image_url}'>",'JG Fortress',
            3 => "<img src='{$image_url}'>",'HT Fortress',
            4 => "<img src='{$image_url}'>",'Ban Fortress',
            6 => "<img src='{$image_url}'>",'Ban Fortress',
    ];
